Spout GBA

The player has to navigate a spaceship upwards through a series of caves, avoiding the walls and the window borders, and getting through the checkpoints before the limited time runs out.

The engine exhaust's plume can (and must) be used as a flamethrower for eroding the cave walls in order to make passages for the ship to go through.

At the title screen, hit spacebar to begin playing. Your goal is to get as high as you possibly can, without crashing or your time running out.
